l and 2, and the screw member 28 is driven against said closure 15, the said screw member 28 will exert a strong pressure from an upward direction against said closure 15 for maintaining the same in a firm contact with the upper end of said cylindrical casing 12 and forming a seal therewith.

Nozzle 30, for receiving sausage casings, connects with the upper end of said cylindrical casing 12, in the very near proximity of said closure 15. A valve operating handle 31 operates a valve in said nozzle for selectively.

opening or shutting off the latter as sausage casings are periodically removed from said nozzle after they have been filled.

Receivable within said casing 12 through the lower end thereof for reciprocating vertical sliding movement therewithin is piston 32. Formed at the inner end of said piston 32 is a diametrical gradually flaring out recess 33, with the wider end disposed in alinement with the opening made in said cylindrical casing 12 communicating with said nozzle 30 whereby food contents within said cylindrical casing 12 above said piston 32 may be directed toward the opening in communication with said nozzle 30 as said piston 32 approaches said closure 15 upon its upward stroke.

. Downwardly depending from said piston 32 in a central relation therewith is hollowed stud 34 defining a socket for reception therewithin of the upper end of piston rod 35. A plurality of radially passed screws 36 engage said piston rod 35 for operatively connecting the same with said piston 32.

By the opposite end said piston rod 35 enters cylinder 37, the lower end of which the latter afiixed in a central relation means of a plurality of screw bolts 39.

The upper end of said cylinder 37 is closed by cover 40, through which a plurality of rods 41 is passed. The

is supported upon base 38, with base 19 by lower ends of said rods 41 are supported in said base 38,,

while the upper ends receive nuts 42 in a threaded relation for clamping said cylinder 37 between said base 38 and said cover 40.

Said cover has a central opening for permitting passage of said piston rod 35 into said cylinder 37. Packing 43, maintained in position by a threaded plug 44 for engaging said cover 40, provides a seal for preventing the escape of fluid from said cylinder 37 past said piston rod 35.

Connected with the lower end of said piston rod 35 is piston 45 positioned within said cylinder 37 for sliding motion.

Supported upon said base and in an encompassing relation with flange 13 and ring 14 is cylindrical wall 46 enclosing said cylinder 37 and the lower end of cylindrical casing 12, as well as the mechanism for imparting reciprocating movement to said pistonrod 35 hereinafter described. A hinged door (not shown) may be provided for said cylindrical wall 46 to afiord access to the space below cylindrical casing 12 and to the hydraulic mechanism for imparting a reciprocating movement to said piston rod 35.

I Supported in any suitable manner upon base 10 is an electric motor said motor 47 is a pair of wires 48 extending from said motor 47 through said cylindrical wall 46 and passed to switch 49 supported in any suitable manner outwardly of and upon said cylindrical wall 46.

Centrifugal pump 50, supported upon said base 10 is operated by means of said motor 47, the latter being shown in Fig. l, but omitted from Fig. 5.

A fluid reservoir 51 is supported in any suitable manner in an elevated position above said base 10 and within said cylindrical wall 46. An inlet pipe 52 connects the lower end of said reservoir 51 and pump 50. A discharge pipe 53 connects pump 59 with a two-way valve, generally indicated by 54. Pipe 55 leading from a two-way valve 54 connects with the lower end of cylinder 37, through base 38, as is seen in Figs. 1, 2 and 5.

47. Upon the electric circuit to operate pipes 53, 55, 56 and 57, depending Pipe 56 connects the two-way valve 54 with the upper end of cylinder 37.

Pipe 57 connects the two-way valve 54 with the upper end of reservoir 51.

Referring now in a greater detail to the construction and operation of the two-way valve 54, the same includes a slide member 58 positioned within the casing of said slide valve 54, the latter being supported by brackets 59 connected with a pair of posts 11. Said slide member 58 is operable by means of rod 60 positioned vertically for shifting movement, and connecting by its lower end to link 61, the latter in a rigid association with the upper end of said slide member 58.

The upper end of said rod 60 extends through said ring 14 and flange 13 and pivotally connects to laterally extending arm 62 of lever 63, the lower end of which is pivoted at 64 to arcuate plate 65, upon which said lever 63 is adapted for angular shifting movement as is seen in Fig. 6. A spring actuated latching bar 66 carried by said lever 63 and co-acting with the rim of said plate 65 is adapted to lock said lever 63 in its angular adjusted relation with said plate 65.

As is seen in Fig. 6 said lever 63 is capable of threefold angular shifting movements. In its position farthest to the left as is indicated by A arm 63 is raised upwardly to the farthest extent, with rod 60 extended in the upright direction to the greatest extent. In the position at C of said lever, arm 62 remains at a horizontal position, and in that latter position rod 60 remains in the neutral position. When lever 63 is extended to the farthest extent to the right, position at B, arm 62 is shifted angularly to the lowermost extent, with rod 60 shifted in a downward direction as far as the same will go.

As is obvious lever at position A will bring about the utmost upright shifting of the slide member 58 within the two-way valve 54, with lever at position B shifting said slide member 58 to the lowermost direction within said two-way valve 54, with slide member 58 remaining at an intermediate point of the two extreme positions mentioned when said lever is at position C.

No detailed description of the two-way valve 54 or its cooperating slide member 58 is required, because the same are quite well known in various arts, both as to theirconstruction and operation. Sulfice it to say that slide member 58 at its portion within the casing of the two-way valve 54 is provided with a plurality of channelled passages in order to interconnect two or more of upon the requirement of the ultimate operative result of the hydraulic mechanism for the purpose of imparting to piston rod 35 a reciprocating motion.

Assuming that it is required to shift piston 45 in an upward direction, from its position shown in Fig. 2, it would necessarily be required to inject fluid through pipe 55, that-is into the lowermost part of cylinder 37, and eject the fluid from the uppermost end :of said cylinder 37 through pipe 56.

For the purpose of accomplishing the result last hereinabove mentioned it may be assumed that the slide member 58 must be in its uppermost shifted position, with lever 63 at position A. When pump 50 is set in operation through the action of motor 47 the fluid from reservoir 51 is sucked into the pump through pipe 52. The centrifugal action of pump 50 upon the liquid supplied thereinto through said pipe 52 is forced through pipe 53 into two-way valve 54 and from there through pipe 55 into the lower end of cylinder 37. Simultaneously pressure upon the fluid above piston 45 is borne thereon through said piston 45 by virtue of the upright shifting of the latter, and the fluid remaining above piston 45 is ejected from said cylinder 37 through pipe 56 into two-way valve 54 and from there through pipe 57 is returned to reservoir 51.

rection to the fullest extent by the operation of the hypiston rod 35 must be made longer. The upper end of piston rod 35 is provided with an axial socket 81. First said upper end of piston rod 35 is disengaged from the hollowed stud 34 on loosening screws 36. Access thereto is had through the door (not shown) in said cylindrical Wall 46. Thereupon extension 82 is fitted over the upper end of said piston rod 35. Said extension 82 is provided at its lower end with a reduced lug 83 (Fig. 3) entering said socket 81. Said extension 82 is suificiently long to permit the shifting of piston 32 beyond the upper end of cylindrical casing 12 for the purpose of washing and cleaning said piston 32. In fact once said piston 32 remains above said cylindrical casing 12 the former may be removed from said extension 82 and piston rod 35 for the purpose of very thorough scrubbing and washing. For the purpose described said extension 82 need not be rigidly connected with piston 32 by tightening said screws 36. Said extension 82 need not be rigidly connected with piston rod 35. Said extension 82 is merely an expedient for bringing piston 32 out of cylindrical casing 12 on imparting to said piston rod 35 an upward stroke by operation of the hydraulic mechanism aforesaid. After said piston 32 has been washed the same may be replaced together with extension 82 upon piston rod 35 and said rod 35 shifted downwardly. Thereupon through the door in said cylindrical wall 46 access may be had under said piston 32 for the purpose of removing said extension 82, replacing the upper end of piston rod 35 within the socket defined by said hollowed stud 34 and thereupon tightening screws 36 to recondition once more said piston 32 for operation after of course closure 15 and bar 16 had been replaced.

Rod 84 in a rigid relation with closure 15 upwardly projects from the latter. The same afiords means for manually grasping for removing said closure 15. Also, when latch 2225 is in an operative position, and before screw 28 has been tightened said rod 84 may be shifted towards said bar 16 until the former comes in contact with the latter to indicate that all parts are in a mutually operated position before screw 28 is tightened to bear against said closure 15.

While there are described herein preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
